fix(std/iter): align example descriptions with closure logic for find and find-index (#15895)

Browse Source 
- Updated the second @example for `find` to "Try to find an even
element" to match the closure logic.
- Updated the second @example for `find-index` to "Try to find the index
of an even element" for consistency.
